Really, my only issue with this is what do you do if the body rejects it?
What do you replace it with?

By starting out slow and only using facial parts, they can always use skin grafts to cover up rejected areas. I'm sure they are mostly doing this on worst case scenarios where a rejection problem wouldn't make that much difference as the people don't go out in the public anyway. I'm sure over time the rate of rejection and perfecting of this procedure will make it a very worthwhile risk for those with extremely severe facial damage. The transplanting of body parts has come a long way from the first heart transplant and medical science is getting better all the time except for curing certain diseases.
